Plenty of elements in Replay, like time rewinding, gravity-flipping, and laser-redirecting, are familiar from other puzzle games, but they're all used well and combined interestingly here. For the true sadists out there, each level also contains a key, and acquiring that key usually requires a number of additional moves: essentially, it's an extra puzzle within each puzzle. It took me about 12 hours to complete Replay, and that's without finding most of the keys or achieving 'gold medal' times, so that's a good amount of game for the $10 price tag.
